Crankshaft -RACING, 51mm stroke, 97mm conrod- Vespa PK125 XL2, PK125 ETS (Ø=24mm cone)
Part no.:
1610010
Description
In order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders.
The quality of the crankshafts is very good and so they resist even highest revs. Especially for the higher capacity engines from 125ccm up they are an optimal supplement to extend the usable speed range of racing cylinders without spitback in the lower speed range.

The PK XL2, ETS 125 shaft also offers the enormous advantage that it has the most stable cone and can therefore cope with much higher forces. In addition, it allows the use of ultra-light pole wheels, with which a better acceleration behaviour can be achieved.
